Embodiment Construction

[0044] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings and examples.

[0045] figure 1 It reflects the specific process of the microgrid load reduction control method considering the incentive demand response, including the following steps:

[0046] 1) Data initialization, let t=0;

[0047] 2) Obtain the total output P of the internal distributed power supply of the microgrid at time t G , the total load P L , the maximum output of energy storage P S and the remaining available hours of energy storage T S , if P G +P S >P L , go to the next step, if not, go to step 8);

[0048] 3) If P G L , go to the next step, if not, go to step 7);

[0049] 4) Calculate the maximum load reduction ΔP of all incentive demand response users max and the average time t required to respond rs , if t rs S and ΔP max >P L -P G , proceed to the next step, if not, go to step 7);

[0050] 5) Calculation o...

Abstract

The invention provides a stimulating type demand response-based micro power grid load shedding control method which comprises the following steps: an aim of minimum dispatching cost is set so as to build a stimulating type demand response-based power grid side economic dispatching model; an aim of minimum user economic loss is set to build a user side response module; moreover, current operation condition of a micro power grid is obtained; the power grid dispatching model and the user response model are subjected to solving operation; according to a solving result, whether to conduct stimulating type demand responding operation or direct loading shedding operation is determined. Via use of the load shedding control method put forward in the invention, demand side resources can be used as substitutable resources for micro power grid distributed electric power generation and energy storage; micro power grid investment and operation cost can be lowered, load power failure frequency and power failure time can be reduced, and reliability of micro power grid power supply can be improved.

Description

technical field [0001] The invention relates to the technical field of load reduction control for power system operation, in particular to a microgrid load reduction control method considering incentive demand response. Background technique [0002] With the rapid development of distributed renewable energy and energy storage, demand-side response and virtual power plants have become key factors in the development from smart grid to energy Internet. The smart grid emphasizes that users actively participate in the operation and management of the grid, and realizes the flexible two-way interaction of power and information between the grid and users. As an important part of the smart grid, demand-side response can respond to electricity price signals or incentive mechanisms and adjust power consumption patterns to realize peak-shaving and valley-filling of the power grid and promote the consumption of distributed power sources. At the same time, as a kind of virtual controllab...
